Dielectric properties of (Sr0.7Pb0.3)TiO3 ceramics were investigated up to 100 kHz down to −260 °C along with temperature dependent thermal strain, X-ray diffraction peaks, and hysteresis loops. The (Sr0.7Pb0.3)TiO3 ceramic showed almost frequency

(Sr0.8Pb0.2)TiO3 (SPT) ceramics would be normal ferroelectrics with relaxor-like character around the Curie point, TC. SPT-MgO composites in the composition range between 0.5 and 5 weight% MgO were prepared and permittivity in the composites decrease

A family of ceramic composites fabricated from (Sr1-xPbx)TiO3 (SPT) and MgO show promise for room temperature electric field tunable ferroelectric applications. At the SPT (x = 0.2) composition room temperature is far above the Curie temperature and

(Sr0.8Pb0.2)TiO3-MgO composite system has been studied by Somiya et al. At room temperature, attractive relative permittivities (over 100) were obtained with an addition of MgO in (Sr0.8Pb0.2)TiO3. At the same time, low relative dielectric losses, ta

Using a composite of a high dielectric permittivity (ϵ) ferroelectric and low ϵ oxide to check dielectric mixing rules, often the high ϵ ferroelectric is strongly sensitive to elastic and dielectric boundary conditions. So its ϵ changes as volume
